96 g
|
|
|
130 g
|
|
|
232.5 g
|
|

Explanation:
Detailed explanation-1: -Molar mass of AuCl3 = Au + 3*Cl => 196.97 + 3*35.45 => 303.32 g/mol => 303.3 g/m…
Detailed explanation-2: -Molar mass of AuCl3=197+3×35. 5=303. 5gm.
Detailed explanation-3: -Molar mass is the mass in grams of one mole of a substance. Its numerical value is equal to the formula mass that is expressed in a.m.u. For example, glucose has a formula mass of 180.0 a.m.u. So, the molar mass (mass in gram of one mole) of glucose is 180.0 g/mol.
